Ah yes, I too conflate bills written by organized lobbyists with a loosely affiliated group that says American shouldn't be ran by Nazi's. The Nazi's running America get very mad about that and ensure to flood the airwaves with how cities in the US are mile wide smoking craters due to people who don't like authoritarians.
The point GP was making, which holds as a general rule, is that simply adopting a moniker does not necessarily mean that it accurately describes you. Your argument pre-supposed that just because Antifa self-describes as antifascist, it inherently is, and that the CEO was expressing an opposition to the concept of antifascism, rather than simply expressing opposition to the specific group.
If Antifa’s record speaks for itself, then you don’t need to play these kinds of word games. If some CEO spoke unflatteringly of The Red Cross or Habitat For Humanity, that would say more about them than anything, not because they have virtuous sounding names (though they admittedly do) but because they’ve established a specific track record of public service.
